Ello,
I am experiencing almost the exact same symptoms, too. I am been diagnosed with migraines in July and I'm only getting to know what my triggers are. I was prescribed lexapro and midrin. So far I still get the random throbbing in the area above my left eye. I also have tingling sensations that crawl up and down the back of my head. I also have random throbs on the temporal and parietal regions of my head. I find that all of this happens before and after a storm. It gets worse around my period. I'm still in the middle of trying to find out what's really wrong with me. I hope that your search ends soon, too.
Ello, has your doc mentioned hemicranial to you? I have headaches on my right side all the time. the pain get sharp just like you mentioned. This is what I was diagnoised with. its a one sided headache. talk to you doc about it. I was perscribed indomethicen, it did not work for me but ya never know??
I often have the same thing about a day before I get a migraine. I feel really bad the whole day, and wake up with pain. I also have it happen when I am under stress or not getting enough rest. I have just learned to drink water (lots) and rest. Hope it helps
